The isomerization reaction H3CNC(g) <=> H3CCN(g) was found to be first order in H3CNC. At 600 K, the concentration of H3CNC is 75% of its original value after 205 s.
(a) What is the rate constant for this isomerization reaction at 600 K?
(b) At what time will 33% of the H3CNC originally present have isomerized?
(c) What is the half-life for this reaction at 600 K?
You need to read about chemical kinetics in your text. Then post what you think your approach should be.
